PROBLEM TO BE SOLVED: To prevent a valve plug from being tightly fitted to a valve seat part until dispensing the next time, and restrict air from being sucked into a container body when the valve plug is seated on the valve seat part.SOLUTION: A dispensing cap 1 comprises a cap body 2 which includes a top wall part 11 covering an aperture of a mouth part 101 of a container body 100 and in which a dispensing hole 4 for dispensing a content is formed on the top wall part 11. On the top wall part 11, a communication cylinder 20 is extended downward for making the dispensing hole 4 communicate with an interior of the container body 100. Inside the communication cylinder 20, there are disposed: a valve plug 24 which is arranged so as to be vertically movable; a valve seat part 22a on which the valve plug 24 is seated so as to be separable upward and which blocks the communication between an interior of the communication cylinder 20 and the interior of the container body 100; and regulating projections 26a for regulating lifting movement of the valve plug 24 in a state that the interior of the communication cylinder 20 and the dispensing hole 4 are communicating with each other. A holding clearance for holding a content is provided between a valve plug 24 surface and a valve seat part 22a surface.SELECTED DRAWING: Figure 1 |
